Ubuntu Wifi not connecting suddenly
My ubuntu laptop wifi was working fine until yesterday. I just connected to my friends modem to check his internet connection and now my laptop's Wifi is not working. The same connection shows connected however with a different symbol (computer icon with wifi symbol inside it) and internet does not work. Ethernet connection seems to be fine which concludes that Internet and router in my home are working fine. Do you think connecting to his modem caused some issue?
Dell Vostro 14 3000 series laptop with ubuntu 12.04.
Can you please help me solve this issue.

Also, reboot your router. Leave it off for at least 30 seconds. Just pull the power and wait, then back in.

The WLAN device is able to scan for access points and finds these:
Is the one that you want to use one of these?
Do you see that list when configuring the network?

No Manfred, the access point i'm searching for is "NETGEAR94" which I have deleted while running the commands. Now I recreated the wifi access point using the "Create new Wi-Fi Network". Again it connects, however instead of wifi sybmol it shows a computer screen with wifi symbol inside it. The wifi shows connected to this access point but the internet does not work.

I think "Create new Wi-Fi Network" was wrong, This let your computer act as a hotspot for other systems to connect.
You should have used "Connect to hidden Wifi network" if NETGEAR94 is defined as not broadcasting its ESSID.
If your computer can list several other WLAN routers, but not your own one, are you sure that it is correctly working?

I am sure that it is working fine since I have been working on it for more than 5 days properly. I just tried to connect again using the "Connect to hidden wifi network" and it is getting connected with the same symbol as I mentioned earlier. Internet is not working after it gets connected.
Router does not have an issue since all the mobiles and laptops are connected and its working fine for them. Infact the same router worked fine even in the night.
What do you want me to do. Delete the current connection and create again ? If yes, how should I do that?
Thanks Manfred for your help in advance.

Yes, try deleting the defined connection, and let the computer search for access points. Do you see a similar list as the one that I wrote in a previous comment? Is your router listed?

Yes Manfred, I see a similar list including the access point that I need but with the same symbol and same internet issue as earlier. I am currently connected to my ethernet.

I assume that your Wlan settings are still creating a hot-spot instead of connecting to your router.
What is the output of the commands
ls -l /etc/NetworkMan
cat -n /etc/network/

As you said yes, I think it is not detecting the network "NETGEAR94" that I want.

If you see several other Wifi networks available, but not your own one, then the problem has to be on your Wlan router.

Have you already rebooted the router?
What is the output of
sudo iwlist scan | grep -Ei 'chan|ssid'

Manfred I rebooted the router once again and somehow it started working again. I am not sure what is the root cause? Kindly let me know your comments on the same.

Netgear94 is what I was looking for and it is connected now. Many thanks for your continuous troubleshooting and help.
